There were many reports of shoot removal on yield of tuberous in cassava. However very little plant physiology research has been done to verify the cause of such yield reduction. The objective of the study was to investigate the effects of time of first hoot removal on the growth and development ...

Ha diversos resultados sobre a influencia negative da remocao dos rebentos no remindimento das raizes tuberosas da mandioca.noentanto,mutio pouco tem sido feito para verificar as causas dessas reduces no rendimento. O objective deste estudo foi ode investigar o effeito da epoca em que a primeira ...

Because of IITA's interest in cassava utilization by humans and livestock, selection for acyanogenesis will be an important objective of the cassava-breeding program. Selection for acyanogenesis will be based on finding cassava lines that lack the glucoside, glucosidase, and/or the glucoside and ...

A cause de l'interet que porte I'IITA a l'utilisation du manioc par I'homme et Ie betail, un objectif important de son programme de recherche sur la genetique du manioc visera a la selection de plants pour leur acyogenese. A cette fin, on tentera de decourvrir des Iignees de manioc depourvues de ...
